I think I've identified the problem - thanks for including detailed debug output 
in your message, this was very helpful.

It's due to how PCA handles the wgetproxy option and the changes in the download 
  procedure on Oracle's side. For any URL it tries to access, PCA looks whether 
it's HTTP or HTTPS, and sets either http_proxy or https_proxy for wget to the 
value set in the wgetproxy option. Now while the primary URL for patch downloads 
uses HTTPS, the last redirect in your example points at an HTTP URL 
(http://aru-llnw.oracle.com/). So wget then tries to access this URL directly 
and not through the proxy, and fails. Before the backend changes, the redirect 
always ended at https://a248.e.akamai.net/, so it was HTTPS for all URLs.

As a fix, I've now changed PCA to always set both http_proxy and https_proxy, no 
matter which protocol is used in the URL to be accessed. Please get the current 
development release and try that:

As to why it works for Michele anyway, I can only guess that on his system the 
proxy settings for wget (both http and https) are already set in e.g. 
/etc/wgetrc or ~/.wgetrc, making PCA's wgetproxy option superfluous. That's what 
I recommend anyway, as like that wget will also work outside of PCA.

Please let me know if this was of help,

Martin.
